Hepatopulmonary syndrome (HPS) is an under-recognised complication of chronic liver disease, affecting 10%–30% of patients with cirrhosis. It involves intrapulmonary vascular dilatations, arterial ...

Methaemoglobinaemia is characterised by the oxidation of the iron component in haemoglobin from a ferrous (Fe² +) to a ferric (Fe³ +) state, forming methaemoglobin (MetHb) and reducing oxygen delivery ...

This large prospective UK study compared five low-cost fingertip pulse oximeters with arterial blood gas measurements and ...

Pulse oximeters use light to measure how much oxygen is in a person’s blood. For most people, a normal pulse oximeter reading is between 95% and 100%, researchers said in background notes. Readings ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the ...

COOH) represents the protonated form of the organic acid, whereas lactate (CH₃CH (OH)COO⁻) represents its conjugated base.

Most people should have a blood oxygen level of 92% or higher, even when doing physical activities or sleeping. If your blood oxygen level drops below 90%, it can be dangerous and requires immediate ...

"Although absolute differences in readings were small, they can result in substantially higher rates of false negatives and ...

Introduction In critically ill patients, individualised strategies for red blood cell transfusion (RBCT) are lacking. The objective of this study is to demonstrate the potential advantages of ...

Critically ill patients with shock had similar outcomes whether blood pressure monitoring was invasive or noninvasive in a randomized trial. Survival, organ failure, and need for dialysis were all ...
